[Evaluation of a neuropsychological test battery with psychiatric and psychosomatic patients]. / Evaluation einer neuropsychologischen Testbatterie an psychiatrischen und psychosomatischen Patienten.

Neuropsychological assessment should be an integral component of clinical psychiatric diagnostics. Yet, the commonly used tests have not been investigated adequately for this population so far. The current study evaluated a clinically approved neuropsychological test battery by analyzing data on 226 mentally ill patients using factor and regression analyses. The extraction of three factors (Speed, Memory, and Executive Functions) proved to be adequate as the tests could be allocated properly. Regression analysis revealed an economical basis assessment consisting of three tests (TAP Alertness, VLMT, and Matrices Test). Based on acceptance, economy, and factorial structure aspects, we recommend the investigated test battery for neuropsychological assessment of psychiatric and psychosomatic patients.

Does prolonged grief treatment foster posttraumatic growth? Secondary results from a treatment study with long-term follow-up and mediation analysis.

OBJECTIVES: Prolonged grief disorder (PGD) is a persistent and disabling kind of grief reaction that can be treated effectively with psychotherapeutic interventions. There has been limited investigation of whether these interventions can also enhance positive outcomes of bereavement, such as posttraumatic growth or benefit finding. DESIGN: As part of secondary analyses in a randomized controlled trial evaluating integrative cognitive-behavioural therapy for PGD (PG-CBT), the posttraumatic growth trajectories in 51 outpatients with clinically relevant prolonged grief symptoms were followed up from baseline up to 1.5 years. METHODS: Immediate treatment effects on posttraumatic growth in comparison with a waiting list control group were evaluated with univariate ANCOVA. Using mediation analysis, we examined the relation between symptom reduction and the short-term treatment effect on posttraumatic growth. For evaluating long-term outcome stability, the immediately treated group and the delayed treatment group were pooled. RESULTS: PG-CBT significantly fostered growth in patients suffering from PGD, with a controlled medium effect size of Cohen's d = 0.60 (completer analysis). This effect remained stable up to the 1.5-year follow-up. Grief symptom reduction mediated short-term treatment effects on posttraumatic growth. However, growth also partially mediated treatment effects on prolonged grief symptoms. CONCLUSIONS: Taken together, PG-CBT was effective in enhancing the participants' perception of posttraumatic growth, but the definite interaction between symptom reduction and posttraumatic growth remains unclear, as both seemed to influence each other's trajectory in the course of treatment. PRACTITIONER POINTS: Integrative CBT for prolonged grief disorder also fostered posttraumatic growth. Post-treatment and 1.5-year follow-up effect sizes for posttraumatic growth were moderate. Whether growth-enhancing techniques are useful in grief treatment needs further research.

Mobility behaviour and driving status of patients with mental disorders - an exploratory study.

BACKGROUND: Driving is an important activity of daily life and an integral part of mobility. However, impact of mental illness on road mobility is widely unexplored. METHOD: Driving status in 1497 psychiatric inpatients (PPs) and a clinical control group of 313 neurological inpatients (NPs) was investigated using a brief questionnaire. RESULTS: 67% of PPs (89% NPs) reported to have a valid driver's licence and 77% of them (92% NPs) reported to regularly use their cars. Within driver's license holders, patients with organic mental disorder (32%), substance dependence (37%) and psychotic disorder (40%) had the lowest proportion of current drivers. Higher educational qualification (odds ratio [OR] from 2.978 to 17.036) and being married/partnered (OR 3.049) or divorced (OR 4.840) significantly advanced the probability of possession of a driving license. Predictive factors for driving cessation were being female, an older age, drawing a pension and having an organic mental disease or schizophrenic disorder. CONCLUSION: Mental disease has a negative impact on driving status and this is especially true for illnesses frequently being accompanied by distinct cognitive impairments. Factors predicting road mobility elucidate the strong relationship with psychosocial status indicating that recovery of driving competence should be an integral goal of treatment strategies.

Efficacy of an integrative CBT for prolonged grief disorder: A long-term follow-up.

BACKGROUND: While some intervention trials have demonstrated efficacy in treating prolonged grief disorder (PGD), data on long-term treatment effects are scarce. METHODS: Fifty-one outpatients with clinically relevant prolonged grief symptoms, who had participated in a randomized controlled trial (RCT), were followed up, on average, 1.5 years after integrative cognitive behavioral therapy for PGD (PG-CBT). Initial assessment procedures were repeated, with PGD symptom severity as the main outcome and general mental health symptoms as secondary outcomes. As results in the immediate and delayed treatment groups (former wait list) were similar, the follow-up data were pooled. RESULTS: Overall, 80% of the original ITT sample could be reached, that is 89% of the 37 treated participants, as well as 8 out of 14 participants who had dropped out of the RCT. The considerable short-term treatment success of PG-CBT was stable; pre to follow-up Cohen׳s d was large, with 1.24 in the ITT analysis and 2.22 for completers. The pre to post-improvement in overall mental health was maintained. LIMITATIONS: Since the RCT wait list group had been treated after their waiting period as well, no controlled long-term outcomes are available. CONCLUSIONS: PG-CBT proved to be effective in the longer run. In comparison to other RCTs on prolonged grief this is the largest sample followed up for this long.
